    Migration from 0.x

    • The only change you have to make is to manually import the .css file:
    import 'viewerjs/dist/viewer.css'
    

    Installation

    Install from GitHub via NPM

    npm install v-viewer

    Usage

    To use v-viewer, simply import it and the css file, and call Vue.use() to install.

    <template>
      <div id="app">
        <!-- directive -->
        <div class="images" v-viewer>
          <img src="1.jpg">
          <img src="2.jpg">
          ...
        </div>
        <!-- component -->
        <viewer :images="images">
          <img v-for="src in images" :src="src" :key="src">
        </viewer>
      </div>
    </template>
    <script>
      import 'viewerjs/dist/viewer.css'
      import Viewer from 'v-viewer'
      import Vue from 'vue'
      Vue.use(Viewer)
      export default {
        data() {
          images: ['1.jpg', '2.jpg']
        }
      }
    </script> 

    Support UMD

    Browser

    <link href="//path/viewer.css" rel="stylesheet">
    <script src="//path/vue.js"></script>
    <script src="//path/viewer.js"></script>
    <script src="//path/v-viewer.js"></script>
    ...
    <script>
      Vue.use(VueViewer.default)
    </script> 

    CommonJS

    var VueViewer = require('VueViewer')

    AMD

    require(['VueViewer'], function (VueViewer) {});

    Usage of directive

    Just add the directive v-viewer to any element, then all img elements in it will be handled by viewer.

    You can set the options like this: v-viewer="{inline: true}"

    Get the element by selector and then use el.$viewer to get the viewer instance if you need.

    <template>
      <div id="app">
        <div class="images" v-viewer="{movable: false}">
          <img v-for="src in images" :src="src" :key="src">
        </div>
        <button type="button" @click="show">Show</button>
      </div>
    </template>
    <script>
      import 'viewerjs/dist/viewer.css'
      import Viewer from 'v-viewer'
      import Vue from 'vue'
      Vue.use(Viewer)
      export default {
        data() {
          images: ['1.jpg', '2.jpg']
        },
        methods: {
          show () {
            const viewer = this.$el.querySelector('.images').$viewer
            viewer.show()
          }
        }
      }
    </script> 

    Direcitve modifiers

    static

    The viewer instance will be created only once after the directive binded.

    If you're sure the images inside this element won't change again, use it to avoid unnecessary re-render.

    <div class="images" v-viewer.static="{inline: true}">
      <img v-for="src in images" :src="src" :key="src">
    </div>
    
    rebuild

    The viewer instance will be updated by update method when the source images changed (added, removed or sorted) by default.

    If you encounter any display problems, try rebuilding instead of updating.

    <div class="images" v-viewer.rebuild="{inline: true}">
      <img v-for="src in images" :src="src" :key="src">
    </div>
    

    Usage of component

    You can simply import the component and register it locally too.

    Use scoped slot to customize the presentation of your images.

    <template>
      <div id="app">
        <viewer :options="options" :images="images"
                @inited="inited"
                class="viewer" ref="viewer"
        >
          <template slot-scope="scope">
            <img v-for="src in scope.images" :src="src" :key="src">
            {{scope.options}}
          </template>
        </viewer>
        <button type="button" @click="show">Show</button>
      </div>
    </template>
    <script>
      import 'viewerjs/dist/viewer.css'
      import Viewer from "v-viewer/src/component.vue"
      export default {
        components: {
          Viewer
        },
        data() {
          images: ['1.jpg', '2.jpg']
        },
        methods: {
          inited (viewer) {
            this.$viewer = viewer
          },
          show () {
            this.$viewer.show()
          }
        }
      }
    </script>

    </viewer>
    rebuild
    • Type: Boolean

      ref="viewer"
      :options="options"
      :images="images"
      rebuild
      class="viewer"
      @inited="inited"
    >
      <template slot-scope="scope">
        <img v-for="src in scope.images" :src="src" :key="src">
        {{scope.options}}
      </template>
    </viewer>

      export default {
        data() {
          images: ['1.jpg', '2.jpg']
        },
        methods: {
          show () {
            const vuer = this.$el.querySelector('.images').$vuer
            vuer.show()
          }
        }
      }
    </script>

      defaultOptions: {
        zIndex: 9999
      }
